Abstract
Transverse-energy distributions have been measured in the pseudorapidity region −0.1<η lab<2.9 for oxygen-nucleus collisions at incident energies of 60 and 200 GeV per nucleon for Al, Ag, and W target nuclei. The cross-section for the heaviest target nuclei at the highest incident energy is measured over 5 orders of magnitude and out to a maximumE T of 200 GeV. Measurements of the differential densitydE T/dη lab as a function ofη lab are presented. In the pseudorapidity region −0.1<η lab<2.9 the transverse energy for an average central collision is proportional to ≈A 0.5, while the fraction of the total transverse energy measured in an extended region ofη lab>2.9 decreases with increasingA. The distributions are compared with the predictions of a dual parton model. Finally the question of the energy density is addressed.
